When you are buying a used generator, choose a dealer who has a history of technical expertise and honesty. Choose a dealer who has a reputation of being reliable. Ask friends, family and neighbors if they know of any local dealers you should make this large purchase from. Because used generators are often sold as “as is” remanufactured units or simply marked as remanufactured units, they usually don’t come with a warranty. Find a reputable dealer who is willing to offer a basic warranty for the used generator. Make sure to ask if the unit comes with a warranty, if it doesn’t, you may want to shop elsewhere. If it does come with the warranty ask exactly what it covers and how long the warranty  is good for. Remember, all dealers do have a responsibility to sell a units that are in working condition. When you are buying a used generator, keep in mind that you should choose one that is manufactured by a company with a good reputation. They should be known for producing reliable, durable, long-lasting units and should stand behind their product.

Ask the dealer if they have any documentation regarding the history of the unit. If you’re lucky, they will have some type of documentation. there are several important factors to take into consideration when it comes to buying a used generator. Find out how old the unit is, how many hours it has been operated, what it was used for and how often maintenance was performed on the unit. If the dealer does have the maintenance records for the generator, check over them carefully. A well-maintained unit that require very little maintenance is a sign that it will be a good investment. Keep in mind that replacement parts may no longer be available for older generators. Every generator has an odometer that records the number of hours the unit was in operation. Make sure the odometer is still working. Check the number of hours the generator was in use. The lower the number, the better. Ask the dealer if he knows whether it was used as a primary power source or if it was only used during emergencies. If it was only used during emergencies, it will probably have less wear and tear. This means it will probably have fewer mechanical issues and will last longer.

You should perform your own inspection of all of the components of the used generator. Look at all of the mechanical components to see if you notice any damage or signs of excessive wear. Look for cracks and corrosion. Sometimes refurbished generators have replacement engines and that engine may not have been made by the same company as the original. If this is the case with your generator, make sure that a certified technician was responsible for placing the engine.

Look over all the welded areas. Make sure there are no cracks. Gently push or talk on the areas to make sure they are not loose. Look at all of the electrical components. There should not be any frayed or worn out areas on the insulated wires. Make sure that all the bearings bushings fasteners and bolts are new. This is really important because these components undergo a lot of stress while the generator is running in their integrity isn’t as easily determined as it is for welding or wires. Make sure the coolant has been replaced. The use generator should also have new belts, hoses and spark plugs.

Finally, make sure the dealer has conducted a load test. A load test determines how well the unit responds to the different degrees of power load demands. It determines the electrical power the use generator puts out under varying load demands. If the dealer does not have documentation that a load test has been conducted, ask him to perform one before you buy the used generator.
